potential more negative. Divalent cations (Ca²⁺ and Mg²⁺) can make kaolinite zeta
potential less negative; while some anions (HCO₃', CO₃²', HSiO₃', H₃SiO₄' and
C₆H₅O?') can make kaolinite zeta potential more negative. Silicate ions have the
largest effect on kaolinite zeta potential change than other anions. This is
consistent with the results in Table 4.10, in which silicate has larger adsorption
equilibrium constants than other ions to make zeta potential of kaolinite more
negative.
